Why Hire TypeScript Developers From Serbia?

StepTo is a Belgrade, Serbia-based software company with a 15–20-person engineering team. Our developers build full-stack TypeScript applications , React and Angular frontends, NestJS and tRPC backends, for European and US companies from the CET timezone, at 40–60% lower cost than Western Europe or the US. Shared type definitions across a codebase are only as reliable as the team maintaining them, so StepTo keeps the same TypeScript engineers on a codebase year after year, with 2.5+ years of average developer tenure.

TypeScript has become the standard for professional web development, bringing type safety, better tooling, and improved maintainability to JavaScript projects. From startups to enterprises, TypeScript enables teams to build more reliable software faster. At StepTo, our Serbian TypeScript developers bring deep expertise across the full TypeScript ecosystem, from React and Next.js to NestJS and tRPC.

Whether you're starting a new TypeScript project, migrating an existing JavaScript codebase, or need senior TypeScript expertise to level up your team, our developers deliver production-ready solutions. We specialize in advanced type patterns, monorepo architectures, and end-to-end type safety that eliminates entire categories of bugs.

Based in Belgrade, Serbia, our TypeScript developers work in the CET timezone, enabling real-time collaboration with European teams. You get senior-level TypeScript expertise at 40-60% lower costs than local hiring, with strong fundamentals in type theory and modern development practices.

What TypeScript Development Services Do We Offer?

StepTo offers six TypeScript development services: full-stack TypeScript, TypeScript migration, API development, type system design, code quality tooling, and consulting.

Full-Stack TypeScript

End-to-end TypeScript applications with React or Angular frontends and Node.js or NestJS backends sharing types across the stack.

TypeScript Migration

Gradual migration of JavaScript codebases to TypeScript with strict typing, improving code quality and developer productivity.

API Development

Type-safe REST and GraphQL APIs with NestJS, tRPC, or Express, featuring end-to-end type inference and runtime validation.

Type System Design

Advanced type system architecture with generics, conditional types, and mapped types for complex domain modeling.

Code Quality Tooling

ESLint configurations, strict compiler settings, automated formatting, and CI/CD type checking for enterprise codebases.

TypeScript Consulting

Architecture reviews, migration planning, team training, and best practices consulting for TypeScript adoption.

Which Frameworks and Runtimes Do Our TypeScript Developers Use?

Our TypeScript developers use TypeScript 5+ with React, Next.js, Angular, and NestJS, across the Node.js, Deno, and Bun runtimes.

What Do Clients Ask About TypeScript Development?

Why hire TypeScript developers from Serbia?

Serbian TypeScript developers combine strong computer science fundamentals with deep TypeScript expertise at 40-60% lower costs than Western Europe or the US. TypeScript has become the default language in the Serbian tech community, meaning our developers have extensive experience with advanced type patterns, strict configurations, and enterprise-scale codebases. CET timezone alignment enables real-time pair programming and code reviews with European teams.

Should we migrate our JavaScript project to TypeScript?

In most cases yes, migrating to TypeScript is worth it: it improves code quality, reduces bugs, enhances IDE support, and makes refactoring safer. The migration can be done gradually, TypeScript supports incremental adoption by allowing .js and .ts files to coexist. We recommend starting with strict mode from the beginning and migrating file by file. Our team has migrated numerous large codebases and can create a migration strategy that minimizes disruption while maximizing the benefits of type safety.

What TypeScript frameworks do your developers use?

StepTo's TypeScript developers use React and Next.js, Angular, and Vue.js on the frontend, all with full TypeScript support. For backend development, we specialize in NestJS for enterprise APIs, tRPC for end-to-end type safety, and Express with TypeScript for lighter services. We also use Prisma for type-safe database access, Zod for runtime validation, and tools like Turborepo and Nx for monorepo management.

Can TypeScript be used for full-stack development?

Yes, TypeScript is one of the few languages that enables true full-stack development with shared types between frontend and backend. Using tools like tRPC or shared packages in a monorepo, you can have end-to-end type safety from your database schema through your API to your UI components. This dramatically reduces bugs, improves refactoring confidence, and speeds up development across the entire stack.

How do you ensure TypeScript code quality?

Code quality is enforced with TypeScript strict mode and comprehensive ESLint configurations carrying TypeScript-specific rules. Our codebases feature advanced type patterns including generics, utility types, and discriminated unions for robust domain modeling. Code reviews focus on type safety, and we use tools like ts-expect-error over ts-ignore to maintain type discipline. CI/CD pipelines include type checking, linting, and automated tests.

What engagement models do you offer for TypeScript development?

We offer flexible models including dedicated TypeScript developers for staff augmentation, full development teams for larger projects, and consulting engagements for migration planning or architecture reviews. Whether you need a senior TypeScript developer to join your existing team or a complete squad to build a new product, we match the right expertise to your needs. Trial periods ensure you can evaluate the fit before committing.
